Constrained Rendering

2. The method of claim 1, wherein each subpixel of the group of subpixels within the display region is entirely within the display region.

3. The method of claim 1, wherein the filter is optimized to minimize a perceived error of the image in an opponent color space once the image is displayed on the display.

4. The method of claim 1, wherein the display has multiple color matrix panels, and wherein the multiple color matrix panels have different subpixel layouts, and wherein the constraint is determined based on a subpixel layout associated with that color channel of the display region.

5. The method of claim 4, wherein a first dimension associated with first subpixels of a first color channel is different from a second dimension associated with second subpixels of a second color channel.

6. The method of claim 5, wherein the first dimension and the second dimension are associated with a subpixel size, a subpixel shape, a subpixel distance, a subpixel position, a subpixel angle, or a subpixel layout.

9. The method of claim 7, wherein the image as displayed based on the array of target color values has a minimum perceived error in the opponent color space.

10. The method of claim 1, wherein the filter is optimized during the optimization process based at least on an opponent space function, a Fourier transform function, or a 2D contrast sensitivity function (CSF) in an opponent color space.

11. The method of claim 1, wherein the display has three display panels for three color channels, and wherein at least two display panels are misaligned to each other.

13. The media of claim 12, wherein each subpixel of the group of subpixels within the display region is entirely within the display region.

14. The media of claim 12, wherein the filter is optimized to minimize a perceived error of the image in an opponent color space once the image is displayed on the display.

15. The media of claim 12, wherein the display has multiple color matrix panels, and wherein the multiple color matrix panels have different subpixel layouts, and wherein the constraint is determined based on a subpixel layout associated with that color channel of the display region.

16. The media of claim 15, wherein a first dimension associated with first subpixels of a first color channel is different from a second dimension associated with second subpixels of a second color channel.

18. The system of claim 17, wherein each subpixel of the group of subpixels within the display region is entirely within the display region.

19. The system of claim 17, wherein the filter is optimized to minimize a perceived error of the image in an opponent color space once the image is displayed on the display.

20. The system of claim 17, wherein the display has multiple color matrix panels, and wherein the multiple color matrix panels have different subpixel layouts, and wherein the constraint is determined based on a subpixel layout associated with that color channel of the display region.
